This page allows a user to get a forecast for an area they design.
An area is created by clicking on the map and placing markers on the map to create a polygon. The forecast returned
will be an average forecast for the entire area.

Click on map to set each marker.

There must be at least 3 markers to make an area.

All markers are draggable and removable (click on a marker to remove it).

Elevation limits (upper and lower) can be set using the drop down menus. Elevations are in feet.

The area size is restriction due to server load considerations. It is currently set to 3000 sq mile. An alert will appear if the area selected is too large.

Once an area is defined, click on "Get Area Forecast".

To start over, click Clear Map.

To save an area, bookmark the forecast page that is returned.

Note: Grids that fall within Marine areas will not be included in calculations.
The term "grid" is an area that is 2.5km x 2.5km in the West, and
5km x 5km in the Mid-West and East.
